Der Wert der Sonographie in der Diagnostik renaler raumfordernder Prozesse^*

Abstract

1. Sonography achieves an accuracy of 93% (n = 55/59) in the localisation of space-occupying lesions in the kidney. Since the method is somewhat laborious, ultra sound, in the form of a slow B-scan, cannot be regarded as an alternative to radiology with an accuracy of 97% (n = 57/59). 2. For a pathological diagnosis, particularly in the distinction between tumours and cysts, sonography, with an accuracy of 98% (n = 54/55) is markedly better than radiology with an accuracy of 50% (n = 21/42). Sonography is approximately equal to angiography, which has an accuracy of 97% (n = 69/71). 3. Sonography is useful and is indicated for: a) the investigation of non-functioning kidneys, b) patients in whom radiographic contrast media are contra-indicated, and c) for puncture of renal cysts.

Erfüllen die urologischen Tumoren die Voraussetzungen für eine sinnvolle Früherkennungsuntersuchung?

“…tastbarer Tumor in 45%, Gewichtsverlust in 28% und Anämie in 21 % [Skinner et al, 1971], Fieber in 37%, Bluthochdruck in 10%, BSG-Anstieg in 53% und abnormale Leberwerte in 10% [Cherukuri et al, 1977\Jacobi, 1975 [Fiegler et al, 1975;Hutschenreiter und Weitzel, 1979], ihre Stellung im Rahmen der Früherkennungsuntersu chung wird zur Zeit in einer prospektiven Studie geprüft.…”
